(RHSA-2006:0117) vixie-cron security update

The vixie-cron package contains the Vixie version of cron. Cron is a
standard UNIX daemon that runs specified programs at scheduled times.

A bug was found in the way vixie-cron installs new crontab files. It is
possible for a local attacker to execute the crontab command in such a way
that they can view the contents of another user’s crontab file. The Common
Vulnerabilities and Exposures project assigned the name CVE-2005-1038 to
this issue.

This update also fixes an issue where cron jobs could start before their
scheduled time.

All users of vixie-cron should upgrade to this updated package, which
contains backported patches and is not vulnerable to these issues.
